Abstract
A digital signal processor for synthetic aperture radar (SAR) data comprising a method of implementing range cell migration correction without the use of an interpolator, and a method of applying phase corrections and memory management to accommodate large squint in the radar sensor. With this method, the image quality of the processed SAR image is improved, particularly in regard to phase and geometric registration.
